Hi Sandeep,
You can not validate the data without creating the idexes or deleting the data from database level.
Deletion program itself has the condition to delete the data if it can read properly from storage.
If you are storing the archiving file to a content server then it's better to select the option as below in object specific technical settings.
store before delete and deletion has to read from storage.
With the above settings you can make sure that deletion program is reading the archive file from content server only. If it can not read properly delete job will get fail.
Please let me know if you have any concerns.
Regards,
Sudheer T
